MMSSTV is a compact program designed for the radio amateurs who want to use the Slow Scan Television transmission method to communicate. The technology allows them to send images via radio by using their computer.

The program allows you to use your personal radio and interpret the messages in order to display images sent by the other party. You can also use the app to send your own image to other radio amateurs from your region.

In order to use the application you need to connect your radio to the soundcard which enables the PC to send and receive the signals. Since the image quality depends on the performance of your sound card you need to make sure it meets the minimum requirements.

This program supports multiple SSTV modes which enables you to receive and interpret the data from various radio devices. When you start the application, the Auto Mode is turned on enabling it to respond to the trigger signals and record the incoming data.

In the main window you can view the transmission log and save the images to your computer. The user can adjust the image properties by changing the brightness, saturation or contrast before saving it to the hard drive.

Additional tools can be accessed from the app menu by specifying the program that you want to use for editing images or the template files. The templates enable you to add text or shapes to you TX image.

Although the functions are well organized, you need to have at least basic knowledge about radio transmissions in order to figure out how to use the application. The included documentation should be useful for beginners.
